Licensing
Do you need a license in Alabama?
Dryer vent installation can be more regulated than cleaning, because work that modifies ductwork or connects to building systems may fall under mechanical or contractor codes in Alabama, and local permits can apply. This certificate documents training rather than licensure, so confirm exactly what your scope involves and verify current Alabama state and local requirements before performing installation work.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
